* You haven't given me problem 5, so there is no way to check it. * I did find a number of corrections to be made and checked every answer. There are two ambiguous questions (topic was monthly finance rate when yearly was already given). These are good enough for a B+ to an A+ based on my years of teaching math. * If there is anything you can't read, let me know; and I will print this as a PDF for you. * Let us know how you did, please. We really care about our customers and want to see you again.

Hi, Brittany, you appear to be a newcomer here -- and we're glad to see you.

*

You might not be aware that no one here gets paid for their time unless the customer accepts or rates an answer. You will see what option you have.

*

In this case, with so many contributors, it might be hard to find which answer to accept or rate. It would be Steve's answer. That would be right above this comment of mine.

*

We hope this worked out well for you and we get to see you in the future.

Yes...I am new to the site so I'm not aware of any particular procedures. I am 100% positive that you got 5 questions wrong and when I get an answer wrong I am not able to go back and answer that exact same question again. Once an answer is deemed wrong a new question is provided (same problem type but different numerical values). Since I agreed to pay an expert/you for your help I was expecting better results. Also you are the 3rd person on this site to attempt to assist me but everyone has given me several incorrect answers. Even though I'm not satisfied with the answers provided I did still pay you in order to fulfill my portion of our agreement.

I have watched this unfold with great trepidation.

*

I suggest you do the following:

Go to Google and do a search on the phrase:

Permutations on the word mathematics.

*

You will get a lot of hits. The most numerous by far will report that the answer is

11! = 39916800

*

Then you will get

11! / (2!)³ = 4989600

*

Which one is the right one? Well, if math was a democracy, it would be the first one, which is even cited on professional/educational and even mathematical sites.

*

But the correct answer is the second one.

*

So which one did your teacher pick? Because, this was one of the earlier questions asked by your teacher.

*

Believe me, in my years as both teacher and department chair, I have found numerous colleagues making atrocious mistakes. Yes, even on their tests! I have had to correct mis-graded final examinations so that students could get course credit.

*

Am I saying that your teacher made mistakes? I can't say that because I have no idea what his or her actual answers were. I do know that any math teacher who resorts to multiple choice exams is at best a C-level teacher.

*

What I suggest is that you entertain the possibility that Steve, among others, provided you with a good set of answers. I know none of my colleagues here personally, but I do know that I have seen very few errors from them - just the occasional lapse any of us are vulnerable to - the kind of thing that might change an A+ to an A.

*

Believe me, I am hard to satisfy when it comes to professional criticism, but the math experts here really know what they are doing, more than most the teachers I have worked with.

*

If you come back in the future, and there is as glaring a discrepancy as the one you cited (5 wrong answers!?), please share with us which problems and (if possible) what the correct answers were supposed to be. A number of customers found that they were entering one decimal place too many and the mindless computer hadn't been told to accept that. That is, the computer rejected the more accurate answer! Even the College Board readers (test graders) on the AP exams don't penalize students for having more accurate answers than required. I should know; I was a reader for AP Calculus for three years!

*

So, best wishes from me and JustAnswer and please come back and visit.

The grading system was automated so I will check to see if he the above mentioned questions can be graded manually. The system does not provide me with the correct answer but if it did I would be happy to supply you with that information. If it is proven that Mijcar's theory is correct I will be willing to change my rating.
